hi again and thanks for listening when windows updated to 11 they removed Mozilla Thunderbird ESR(x86en-us) publisher Mozilla version 140.5.0 it contained alot of data, address book and many emails. Very disappointing. Is there any thing you could do or is it forever lost thanks again geoff

I am trying to clear some out dated stuff off my computer to make some room on my dreive, and have discovered several older versions of Firefox, saved in a file, Can I uninstall them or delete them - I am worried that this might affect my newer version.
